Product Description

The RAC3.5-100-460-L00-W1-220 main spindle drive controller is one of the several such RAC devices from Rexroth Indramat. The drive helps in controlling asynchronous main and frameless spindle motors. The spindle drive features high-resolution feedback for low speeds. The drive controller can be connected directly to a three-phase power supply. In case there is a power failure, the drive makes the main spindle come to a resting position. The unit can be cooled with the help of air from either inside or outside the control cabinet. It also supports hose cooling if the slits cannot be fit into the control cabinet’s back walls. A hose is used from outside the cabinet to draw in the cooling air and blow it out. The device makes use of mounting accessories for hose cooling.

We can send you the main spindle drive controller to your specified address, with assistance from our partners and their worldwide network. The CNC controller interface of the drive controller has analog and monitor outputs along with controller input. The drive controller features an analog speed set-point with a +/-10V power supply to help in connecting standard CNC controls. It also supports a serial interface for the parameter values to be stored and loaded using a PC. The accessory is not protected against water. The unit is manufactured according to DIN VDE 0160 specifications so that it can be installed in a closed housing or a control cabinet.

The cooling fan has IP 24 protection category while the control cabinet has an IP 54 protection category for its inside. The RAC drive controller can emit heat over the heatsink that is inbuilt in the unit. The internal and external power dissipation of the unit is dependent on the workload. The accessory features 92A continuous controller current rating. It must be stored and transported within a temperature range of -30°C and +85°C. The device comes with a one-year warranty period.
